May 17 [1775].  This afternoon Dr. Richter brought from Bethabara a package of letters; Gemein Nachrichten and newspapers, from Bethlehem and Lititz, which Christian Conrad brought on his return from Pennsylvania. The letters were of April 25th and May 1st, and among other things mentioned the unpleasant fact that about April 19th there had been a skirmish near Boston between the royal troops and the Provincial Militia. The most recent newspapers report that the Congress held in Philadelphia has been declared a Rebellion by Parliament, although Congress vehemently declared its loyalty to the King.
